Hormonal Therapy

Hormones are chemicals circulating in your bloodstream that are produced by glands in your body. Hormonal therapy is used to keep cancer cells from receiving estrogen and progesterone, which they need for growth. If tests show that your cancer cells contain estrogen, progesterone and/or testosterone receptors, hormone therapy is used to block the way these hormones help the cancer grow. Hormonal therapy may include the use of drugs to change hormones' action or surgery to remove the body parts in which produce hormones.
